Quick Verdict
If you run an online store or SaaS business and need developer-friendly tools, Stripe is the winner. If you’re a freelancer or solo operator who just wants a simple way to send invoices and get paid fast, PayPal still works fine. And if you have a physical retail shop or do pop-ups, Square is the obvious choice.
But here’s the honest truth: most small businesses should start with Stripe. It offers the best mix of features, transparent pricing, and global reach. PayPal is a close second for simplicity, but its hidden fees and clunky dashboard can frustrate you as you scale. Square is the king of in-person payments but lags behind online.
In 2026, the payment processor landscape hasn’t changed dramatically, but a few key updates matter. Let’s break it all down.

What Is Stripe?
Stripe is a payment infrastructure platform. It’s not just a “PayPal clone” – it’s a set of APIs that let you build exactly how you want to accept payments. Founded in 2010, Stripe now processes hundreds of billions of dollars annually. It’s the backbone for companies like Shopify, Lyft, and DoorDash, but it also works for a solo freelancer.
The key thing about Stripe is that it’s developer-first. If you can write a few lines of code (or use a no-code tool like Zapier), you can customize your checkout flow completely. Stripe Checkout is a prebuilt hosted payment page that looks professional and converts well.
For small businesses, Stripe offers:
- Stripe Billing (subscriptions, invoicing, metered billing)
- Stripe Connect (marketplace payouts)
- Stripe Terminal (in-person card reading)
- Stripe Atlas (incorporate a US company)
- Stripe Tax (automated sales tax calculation)
It’s not perfect – the dashboard can be overwhelming, and customer support is mostly email/chat (no phone for basic plans). But the reliability and feature depth are unmatched.
What Is PayPal?
PayPal is the old guard. Founded in 1998, it was the first mainstream digital wallet. Today it’s owned by eBay (well, not anymore – spun off in 2015) and still widely used. For small businesses, PayPal offers:
- PayPal Payments Standard (buy now buttons)
- PayPal Payments Pro (custom checkout, $30/month)
- PayPal Here (card reader for in-person)
- PayPal Invoicing (free, with reminders)
- PayPal Checkout (hosted page)
PayPal’s biggest advantage is trust. Millions of people already have a PayPal account and prefer to pay with it. If you sell to consumers who are wary of entering credit card info on a new site, PayPal gives them comfort.
But PayPal has gotten worse over the years. The fees are higher than Stripe for online transactions (2.99% + $0.49 vs 2.9% + $0.30). They hold funds for up to 21 days for new sellers. And their chargeback policy is notoriously seller-unfriendly.
Still, for a freelancer sending invoices to clients who demand PayPal, it’s hard to avoid. And the PayPal Business Debit Card gives you 1% cash back on purchases – a nice perk.
What Is Square?
Square started in 2009 with a simple idea: let anyone accept credit cards with a tiny card reader plugged into a phone. Today Square is a full ecosystem: payments, POS, online store, appointment booking, payroll, and even business loans.
For small businesses, Square shines in three areas:
- In-person payments – The best hardware (Square Reader, Square Stand, Square Register) and software (Square POS) for retail and restaurants.
- Transparent pricing – No monthly fees for basic accounts. Flat rates for all card types (including Amex). No hidden fees.
- Fast funding – With Square Checking, you can get next-day deposits (even on weekends) for a small fee.
Square’s online payment tools are decent but not as powerful as Stripe. The API is good but not as flexible. And Square only works in a handful of countries – if you plan to sell globally, Stripe is better.
Square also offers a free card reader (just pay shipping) and a free POS app. For a coffee shop or boutique, it’s the obvious choice.

- PayPal: $20 per chargeback – non-refundable even if you win. This is a huge pain point.

Winner on pricing: Stripe – lower online rates, lower chargeback fees (refundable), no monthly fee for basic. Square is cheaper for in-person. PayPal is the most expensive overall.

Who Should Choose Stripe?
Choose Stripe if:
- You run an online business (e-commerce, SaaS, membership site).
- You need subscriptions with advanced features (metered billing, coupons, dunning).
- You sell internationally or plan to.
- You have some technical ability (or a developer) to customize the checkout.
- You want the lowest online transaction fees overall.
- You use tools like Zapier, HubSpot, or ConvertKit and need deep integrations.
Stripe is the best all-around payment processor for small businesses that operate primarily online. It’s not the easiest to set up, but it’s the most powerful.
Who Should Choose PayPal?
Choose PayPal if:
- You’re a freelancer or solo operator who sends invoices to clients.
- Your clients expect to pay via PayPal (common in creative industries, consulting).
- You want a simple button or link to accept payments without any coding.
- You need buy now pay later options (PayPal Pay Later is widely used).
- You don’t mind higher fees for the convenience of an existing user base.
PayPal is still the go-to for many freelancers because of its ubiquity. But be aware of the fund holds and chargeback fees. If you can, use Stripe for online payments and keep PayPal as a secondary option.
